Epoch time counts seconds elapsed since 00:00:00 UTC on 1 January 1970, ignoring leap seconds.
Formula and working
UTC date = 1970-01-01T00:00:00Z + epochSeconds; Days since epoch = epochSeconds ÷ 86400
- 1
Collect the inputs
Epoch timestamp (seconds) = 1,700,000,000
- 2
Apply the formula
UTC date = 1970-01-01T00:00:00Z + epochSeconds; Days since epoch = epochSeconds ÷ 86400
- 3
Result
UTC date and time = 2023-11-14 22:13:20.000 UTC
